REMOVABLE SPUR FOR SHOES.

Application filed October 27, 1916.

To all whom it may concern:

Be it known that I, CARL G. CLIFFORD, a citizen of theUnited States, residing in Manila, in the Philippine Islands, have invented new and useful Improvements in Removable Spurs for Shoes, of which the following is a specification.

This invention relates to improvements in means for preventing shoes from slipping, and has as its principal object the provision of means which may be readily applied to the soles or heels of shoes, either when the same are manufactured or by a shoemaker at any time, the device being such that when not in use there is nothing to impede travel or interfere in any way with the ordinary use of the shoe, but when in operation to present a plurality of spurs which will effectually prevent the slipping of the shoe.

This object is attainedby the novel design, construction, and combination of parts hereafter described and shown in the accompanying drawings, forming a material part of this specification, and in which Figure 1 is a perspective view showing the lower part of an ordinary shoe, and the preferred embodiment of spur attaching means. I

Fig. 2 is an enlarged sectional view, taken through the sole of the shoe, and also through the device, the section being taken on line 22 of Fig. 3.

Fig. 3. is an assembled plan view of the entire device.

Fig. 4: is a plan view of the inclosing frame.

Fig. 5 is a similar view of the blank cover disk presented when the spurs are not in use.

Fig. 6 is a reduced plan view of the device, and

Fig. 7 is an enlarged sectional view, similar to Fig. 2, but showing the disk engaged in the face of the frame.

While the application of this invention may be made to almost any style of a shoe, it is particularly appropriate for the use of athletes, ball-players and others who re-- quire a firm foot-hold on the surface upon which they stand, necessitating in most cases the use of shoes specially made for this purpose.

In .the present invention, the sole of the shoe is indicated by the numeral 10, the heel 11, and the upper part of the shoe by Specification of Letters Patent.

ings 14, firmly securing the frame in position.

The ring 16 is formed with an internal thread 18, adapted to receive the disk 20 and also the ring element 22 having a plurality of arms 23, the outer ends of which are extended at a right angle forming spurs 24, adapted to engage the soil or ground trodden upon, the periphery of the ring 22 being screw threaded to engage with the threads 18 of the frame.

The device is further held in position by a central screw threaded stem 26, having its inner end 27 upset or riveted below the bottom of the frame 15, and furnished with an enlarged head 27, the same being flush or level with the edge of the annular ring 16 and adapted to enter the counterbored portion of the central opening 21 in the plate 20, preventing it from becoming removed from the frame.

In the ring 22 is a lug 30 to which is secured by the rivet 31, a spring element 32 adapted to engage in a recess 33 formed in the ring 16 so as to prevent removing the ring 22, except the spring 32 be raised upward, it springing into engagement as the ring carrying the spurs 24 is screwed downward into operative position in the frame.

When it is not desired to make use of the spurs, the plain disk 20 having a screw threaded peripheral edge is screwed outward in the ring 16 by means of a wrench suited to the openings 36, thereby preventing the entrance of dirt within the body of the frame.

When it is desired to use the spurs, the disk 20 is screwed downward into the frame and the ring 22 carrying the spurs 24, inserted in its place in the frame, the spur elements when not in use being removed and readily carried in the pocket of the wearer.

From the foregoing, it will be seen that a spur device is described which can be readily attached to ordinary shoes and operated in such manner as to prevent slipping during the excessive thrust which is often brought to bear upon them while the wearer is engaged in athletics-ports and' the like, and it will also be evident that the spur elements are readily disengageable and the opening covered by the plain disk, level or flushed with the surface of the shoe when the shoes are to be used for walking only.

Having thus described my invention, what I, claim asnew, and desire to secure by. Letters Patent, is

1. In a; device of: the class described, the combination with a circular: frame,. having a disk element and a raised marginal,

ring, said? marginal ring; containingscrew threads, and meansfor! securingtsaid frame to a shoe,. of a ring'engageable within the threads of ,saidtri-ng, means for holding said latter ring inposition, means for engaging or disengaging; said latter ring from said frame, and a plurality of spurs integrally formed with the. lastinamed ring..

2. In a deviceofthe class-described, the

combinationwith a cylindrical frame having afclosedx. bottom, means: for securing said combination with a circular frame, and a base formed therewith, said base having means-for attachment to a support, of a disk screw threaded lntoisaid frame, means for.

raising or lowering said clislgmeans preventing the removalof' said disk, a ring engageable 1n saidframe, means for locking said'ringwhenin an-engagedposition, and

aplurality of spurs extending outwardly from said ring.

In testimony whereof; I- have signed my.

name to this specification.
